Based on everyone’s feedback, we present draft #2 of the OHI Gulf of California regions. We now define 9 subregions (vs. 11), and some of the boundaries have shifted from those proposed during the 1st Expert Working Group meeting. We now incorporate the POEM region information. However, the subregions are still defined by state and major ecoregion boundaries; and the boundaries are still hierarchical such that each subregion is contained with a single state and ecoregion.
If, after reviewing the map and our questions, you have any concerns or comments about these region delineations please email us or connect with us on Zoom at one of our open office hours. This helps us move forward to the next steps!
If you would like to meet over Zoom instead of writing an email, we will have open office hours on:
- need to make new times….

Gulf of California subregions (draft #2)
In addition to state and ecoregion boundaries, we now incorporate the POEM boundaries into the OHI Gulf of California map. The POEM regions have served as a regional framework for collecting and reporting data, and consequently, people are familiar with these regions and some data are reported at this scale.
Open this tab to explore map of POEM regions
To create the current OHI Gulf of California map we assigned each of the >120 POEM regions to the nine general regions identified by the Expert Working Group.
OHI 7 subregions (Draft #2)
The boundaries are as follows:
Upper Gulf (subregions 1 & 5): Follows the boundary of the Biosphere Reserve. The southern border of the Baja side is located around San Felipe; and for the Sonora side the border is at Puerto Peñasco. The line dividing is more/less half the upper Gulf Biosphere reserves.
Midriff Island (subregions 2 & 6): The Baja (subregion 2) boundary goes from San Felipe to the state line where Baja Sur begins; the Sonora boundary goes from Puerto Peñasco to El Choyudo (site paper here). The internal boundary is wider on the Sonora side so it includes San Esteban, Tiburon, Tuner/or Datil, and San Pedro Martir Islands.
Central Gulf (subregions 3 & 7). The Baja side (subregion 3) goes from the Baja Sur state border to just north of Loreto. The Sonoran side goes from El Choyudo to the Sonora/Sinaloa state border.
Southern Gulf (subregions 4, 8, 9). The Baja side (subregion 4) goes from just north of Loreto to Cabo San Lucas. Region 8 starts and ends at the Sinaloa state borders. Region 9 starts at the Nayarit state border and stops at the northern tip of Jalisco (at Cabo Corrientes) so that the the entire Bahia de Banderas Bay is included.
Region 9 Southern Gulf - Nayarit/Jalisco: the coast of Nayarit, including the entire Bahia de Banderas Bay, which includes part of Jalisco, to Cabo Corrientes.
Open this tab to review the original map (and explanation of changes)
Primary changes from original map: - For the northern regions (1+6): The boundaries were moved north so the region includes only the Biosphere Reserve. We also avoid the mouth of the River. - For region 7 the boundary goes further south (moved from Kono to el Choyudo). - Regions 4 and 5 of Southern Baja Sur combined. - Regions 9 and 10 within Sinaloa combined (the coast of the Sinaloa state is very similar, mainly mangroves and sand/mud flats, with few rocky areas).
OHI Subregions by State and Ecoregion
We can also show how the regions align with ecoregion and state boundaries.
